Debt avalanche calculator: the method that minimizes interest
The debt avalanche pays the highest-interest debt first, saving the most money in total interest. A debt avalanche calculator orders your debts by APR, computes the payoff timeline, and the calendar turns the math into scheduled payments.
- Highest APR first
Every extra dollar attacks the most expensive debt — total interest minimized.
- Payoff dates computed
Each debt's clearance date is visible on the calendar.
- Scheduled payments
Recurring payments keep the order and the timeline honest.
- Free core
The calculator and calendar are free forever.
How the avalanche works
List debts by interest rate, highest first. Pay minimums everywhere except the top debt, which gets every extra dollar. When it clears, roll the payment down the list. The math saves the most interest; the calendar keeps the months visible so the method stays believable.
